Overview
Pharmaceutical grade nicotinamide is a high-purity form of nicotinamide, essential for human health as a precursor to coenzymes NAD and NADP. It plays a critical role in cellular energy production and DNA repair. Unlike nicotinic acid, it does not cause skin flushing, making it preferable for medical and cosmetic applications. Its production involves stringent quality controls to meet pharmacopeia standards such as USP, EP, and JP. This ensures its safety and efficacy for use in pharmaceuticals and dietary supplements. The compound is widely recognized for its stability and bioavailability.
Physical and Chemical Properties
Pharmaceutical grade nicotinamide appears as a white crystalline powder with a molecular weight of 122.12 g/mol. It has a melting point of 128-131°C and is highly soluble in water and ethanol, which facilitates its formulation into various dosage forms. The compound is non-hygroscopic and stable under normal storage conditions. Its density is approximately 1.40 g/cm³, and it exhibits excellent thermal stability, making it suitable for high-temperature processing in pharmaceutical manufacturing.
Main Applications
Nicotinamide is widely used in the pharmaceutical industry for treating pellagra and other niacin deficiency disorders. It is also incorporated into skincare products for its anti-inflammatory and brightening properties. In the dietary supplement sector, it is a key ingredient in multivitamins and energy-boosting formulations. Additionally, its role in cellular metabolism makes it valuable in medical research and therapeutic applications, including cancer treatment and neuroprotection.
Safety and Storage
Pharmaceutical grade nicotinamide is generally safe when used as directed. However, prolonged exposure to dust should be avoided to prevent respiratory irritation. Proper storage in a cool, dry place away from light and moisture is essential to maintain its stability. Handling should follow standard laboratory safety protocols, including the use of personal protective equipment (PPE) such as gloves and masks. In case of accidental ingestion or contact, seek medical advice promptly.
B2B Procurement Guide
When procuring pharmaceutical grade nicotinamide, prioritize suppliers who comply with international pharmacopeia standards (USP, EP, JP). Verify certificates of analysis (CoA) to ensure purity and quality. Bulk purchases typically offer cost savings, with prices ranging approximately $20-$50 per kg depending on quantity and purity. Consider long-term partnerships with reputable manufacturers to ensure consistent supply and quality assurance.
